Product Description

PRODUCT HIGHLIGHTS

Magnesium hydroxide is a premium green inorganic functional material that stands out in modern industrial applications for its balanced performance and eco-friendly attributes. It presents as fine, odorless white crystalline powder, with non-toxic, non-corrosive and non-irritating properties that make it far safer to handle than traditional strong alkaline agents like caustic soda or industrial lime. As a high-efficiency halogen-free flame retardant, it features a stable decomposition temperature above 340 degrees Celsius, perfectly matching the high-temperature processing requirements of engineering plastics, rubber products, wire and cable insulation materials. When exposed to flame, it absorbs massive heat to cool the combustion surface, releases water vapor to dilute flammable gases, and forms a dense magnesium oxide protective layer to block oxygen and suppress smoke. It produces no toxic or corrosive fumes during the whole process, fully complying with strict EU RoHS and REACH environmental regulations for electronic and automotive material applications. In wastewater treatment, its mild and sustained alkalinity can adjust the pH value of acidic sewage stably without causing sudden over-alkalinity that damages equipment. It efficiently precipitates heavy metal ions such as nickel, lead and cadmium, and removes over 35% of sulfides in water to reduce pipeline corrosion and odor emission. It also improves sludge flocculation and dewatering performance, cutting the overall operating cost of sewage plants by more than 20% compared with traditional neutralizers. This product has excellent thermal stability, no risk of deliquescence or agglomeration during long-term storage, and supports long-distance transportation without special anti-corrosion packaging. It also performs well in flue gas desulfurization, food processing, antacid pharmaceutical production and other scenarios, with all quality indicators strictly meeting national industrial standards. Its high cost performance and wide application adaptability make it a preferred reliable choice for enterprises pursuing green and safe production.

ABOUT THE SUPPLIER
Hebei Runhuabang New Material Technology Co., Ltd stands as a leading manufacturer and supplier of high-quality calcium carbonate, dedicated to delivering premium-grade products that cater to the evolving needs of diverse industries worldwide. With a core focus on producing calcium carbonate ranging from 200 to 8000 mesh, covering heavy calcium carbonate (GCC), light calcium carbonate (PCC) and surface-modified calcium carbonate, the company has established itself as a reliable partner for businesses seeking consistent performance, superior quality, and compliance with international standards. Calcium carbonate, a naturally occurring inorganic mineral composed primarily of calcium carbonate (CaCO3), is renowned for its versatile properties-such as high whiteness, good dispersibility, stable chemical properties and non-toxicity-that make it an indispensable ingredient in numerous industrial applications. Hebei Runhuabang's calcium carbonate is sourced from high-quality natural calcite and limestone deposits, ensuring a pure and consistent base material that serves as the foundation for its exceptional performance. The company's commitment to quality begins at the sourcing stage, where rigorous geological surveys and mineral testing are conducted to select deposits with optimal chemical composition and physical characteristics, ensuring high calcium carbonate content and low impurity levels. This meticulous approach guarantees that every batch of calcium carbonate meets the strictest purity requirements, free from harmful impurities and contaminants. One of the key strengths of Hebei Runhuabang calcium carbonate is its superior whiteness and high purity, critical attributes for applications where aesthetic appeal, color consistency and product performance are paramount. The high whiteness level of the product enhances the visual quality of finished goods, whether used in plastics, coatings, paper, or building materials.
